Microsoft built a brand new browser for Windows 10 called Edge, though it isn't proving as popular as the operating system it comes bundled on. One way Microsoft hopes to change that is by adding a new prompt when users install a third-party browser like Google Chrome and attempt to switch defaults.

The prompt appears in a leaked preview build of Windows 10 (build 10568), so it might be only a matter of time before it's implemented in Windows 10 through a future update. If so, users who try to switch their default browser from Edge to something else will see a prompt that says "Give Microsoft Edge a shot," followed a short of list of features. It reads as follows:

Before you switch defaults, see what you can do in an app built just for Windows 10:

Write on webpages and share our ideas

Read distraction-free with reading view

Get answers in the browser from Cortana, your personal assistant (where available)

You have two options: click the highlighted "Don't switch and try it now" text or select "Switch anyway," both of which appear at the bottom of the prompt.

This is Microsoft's latest effort to promote Edge and we wouldn't be surprised if Mozilla took issue with it. When Windows 10 first launched, Mozilla CEO Chris Beard wrote an angry blog post blasting Microsoft for implementing an upgrade process that "appears to be purposely designed to throw away the choices its customers have made about the Internet experience they want, and replace it with the Internet experience Microsoft wants them to have."

Windows 10 is now installed on more than 110 million devices. Meanwhile, Edge is slowing expanding its footprint with a 2.4 percent share of the browser market, according to data by Net Applications.
